Powertrain Upgrade

This script adds two configuration lines to every motorized vehicle: "Engine Power" and "Top Speed". Choose your setup at purchase or change it anytime in the workshop – no duplicate entries in the shop, and it works seamlessly with mod vehicles too.

Seven tiers are available for each option: Stock / +25% / +50% / +100% / +150% / +200% / +500%. Each tier costs a fraction of the vehicle's price, scaling naturally from a small farm tractor to a 500 HP flagship. Engine power and top speed can be configured independently.

The entire drivetrain is recalculated dynamically: torque curve, peak torque, attachment power, clutch limit, acceleration limit, and fuel consumption follow the power tier. Transmission ratios, forward/reverse top speed, clutch behavior, braking force, and cruise control limit follow the speed tier. For CVT transmissions, only the upper speed range is extended – the slow fieldwork range remains untouched.

Because real vehicle configurations are used, the game itself handles pricing, savegame persistence, and multiplayer synchronization. Top speed is capped at 160 km/h.
